$500 build help

[pinoy16]

1) What will you be doing with this PC?
Light gaming (WOW, SC2 and Rift).

2) What's your budget? Are tax and shipping included?
$500-550 after tax and shipping

3) Where do you live?
Raleigh, NC

4) What exact parts do you need for that budget? CPU, RAM, case, etc. The word "Everything" is not a valid answer. Please list out all the parts you'll need.
CPU, Mobo, Ram, HD, DVD burner, PSU, Case, Video Card

5) If reusing any parts, what parts will you be reusing? Please be especially specific about the power supply. List make and model.
Will not be using any previous parts

6) Will you be overclocking?
No

7) What size monitor do you have and/or plan to have?
22", 1680x1050

8) When do you plan on building/buying the PC?
ASAP

9) What features do you need in a motherboard? RAID? Firewire? Crossfire or SLI support? USB 3.0? SATA 6Gb/s? eSATA? Onboard video? etc.
I don't need any features except for the typical.

10) Do you already have a legit and reusable/transferable OS key/license? If so, what OS? Is it 32bit or 64bit?
Yes, Windows 7 64

I'm mainly confuse on what CPU, Mobo and Video card to get. I haven't built a PC in 2 years and not to sure what AMD/Intel currently offers. Would love to have a quad core if at all possible. From what I have seen, I'm thinking a Phenom II might fit the budget. As far as the video card, a 4850 might be powerful enough since I don't think my resolution will bog it down too much.

So far I've got.
$40 Gskill 4GB
$60 Antec BP550 Plus
$60 Western Digital Caviar Black 640

Thanks for the help guys.

Total: $546 shipping

Notes:
- The video card and CPU are sale prices that probably only last till midnight tonite. As such, if you can, get the CPU and video card FIRST. Those are really good prices for those two parts. If you had to get them at normal pricing, it would have bumped up the costs by another $50. So definitely get those two parts ASAP especially since Rift and WoW are rather CPU and GPU heavy even at your mid-range resolution

- The WD 500GB drive is actually faster than that WD 640GB drive due to better platter design and density.

- That Antec 550W PSU that you chose is not worth $60. The extra $4 for the ANtec Neo Eco 520C is well worth it due to the sheer difference in quality between the two PSUs.
